Delete a File & Rescan?

Hey, so I just got the WD TV Live SMP and am having a small issue.  I have a media library setup that looks at my local attached storage (2TB) and a network folder on my computer.  Under media library I have folders on the network and if inside one of those folders I delete the only file inside that folder, it still shows that folder, while I would prefer (and think that it is suppose to) no longer show that folder since it is empty.  I have tried rescanning the folders and it still remains.  Any one else experienced this or know what I can do?

Thanks!

The folder will show up, even if it is empty.  You may submit this as an Idea:  WD TV Live Streaming Ideas

But if you turn off the WD TV Live SMP and turn it back on, it will not show the empty folders in media library.
